Overview
A basement, garage, cabin or metal building often blocks the signal that this kit is meant to lift. An outdoor directional antenna catches the tower signal, the booster amplifies it, and an indoor whip antenna rebroadcasts it inside.
The reason to consider it is the complete kit: both antennas, power supply and manual arrive together for a weak-signal room. The limit is the single band, so it helps only phones on that Verizon network, and the compatible devices entry reads oddly for a phone product.
Who it's for
A rural home, metal roof building or garage where calls drop and data stalls. Users on other networks, apartment dwellers without roof access, or anyone needing whole-building coverage should look at a multiband model.
Pros and cons
- Antennas and power supply included
- Targets Verizon and Straight Talk
- Works with 5G and 4G LTE phones
- Two year manufacturer warranty
- Single band only
- Boost amount not stated
- Needs outdoor antenna placement
- Compatible devices entry looks wrong
Performance notes
The result depends mostly on how strong the outside signal is where the directional antenna points, because a booster amplifies what it receives and cannot invent signal. Separating the two antennas lowers the chance of feedback loops. Coverage beyond the stated range depends on walls and building materials.

Frequently asked questions
Will the Gagbk booster work on AT&T or T-Mobile?
No. The listing names Verizon and Straight Talk on Band 13 only.
Does the booster create a signal where there is none?
No. It amplifies an existing outside signal, so the outdoor antenna needs some reception to work with.
What is in the Gagbk booster box?
The listing names the booster, a 12V 2A power supply, an English manual, an indoor whip antenna and an outdoor directional antenna.
Does it boost TVs and computers?
The compatible devices entry names a television, computer and tablet, but the product is described as a cell phone booster for Verizon voice and data.
